Letters-Patent No. 97,905, dated December 14, 1869.

IMPROVEMENT-IN FIELD ROLLERS.

. The Schedule referred to in these Letters Patent and part of the same.

To alQwhom it man concern: 1 I v .Be it known that I, ROBERT GLovER, of Tonawanda,'in the county of Erie, and State of New York,

have invented certain Improvements infield-Rollers;

of which'thefollowin'g isa specification. v

My invention relates to field-rollers, in which 'three roiling-surfaces are used, and eousistsin the arrangem'ent'of parts whereby the outer rollers may be elevated, as hereinaiterdesciibed.

r The rear sides'of this frame are attached by hinges a a, to supplementary frames 0 0', in which run, respectively, rollers D D. r r

- The front rollcrA is made with: enough to overlap the path ofthe rollers'D D, so that the entire surface pals-sell. overis evenly rolled, without leaving creases or .ri ges;

The hinging of the frames B O' 0' together allows a important on uneven ground. I To facilitate passing over hilly land, and, also, over stumps, large stones, and other obstructions, I form a triangular derrick or frame, E, on the top of,an'd attached to the centre frame B,'just' back of the drivers seat I).

i in this derrick or frame E, I arrange two wind- Iasses, c c, the ci anks of which can be operated by the driver, one by the right hand, and the other by the left. i

'Aronud each \vimllass ispassed a rope or chain, (1 d',-one end of which is fastened to the outside of frames 0 C, and by turning the; crank of either or both wiudlasses, the outside rollers are raised up to any degree for the purpose above named, or to pass This is an important feature of my invention, which no other roller possesses, that. I am acquainted with.

To balance and sustain the centre frame, when the i play up and down of side rollers DfD, which is very "side rollers are raised, I place. a wheel, F, back of the front roller A, and attached to the back of the centre frame B, so that it partly sustains the weight of the machine, as above stated. This is also an important feature, as without it the whole'machine would tip .over back-ward. v

Anovel feature of my invention consists in at the same time so arranging said side rollers that they may beelevated, as shown by the dotted lines in fig.- 2. Thus a wide or narrow sweep may be formed, as circumstances require.

When the side rollers are not in use,- they may be detached from, or used to weight the centre roller.

Iain acquainted with the patent of H; R. (ll-owe,

I March, 12, 1869, which shows three rollers, two of them hinged upon arod, and the third fastened to the endof it. I a

' This not the equivalent of my invention, and he has to use one roller detached, or the three together, and they cannot be raised and lowered, like mine.

There are other patents that I 'am acquainted with,

showing three rollers, some of them with a roller be-.

bind, and the two rpnning on a single shaft. They -are not hinged or arranged like mine, and none of them possessthe balance-wheel.

I claim 1.v The triangular frame or derrick E, having Wind- D, balance-wheel F, derrick E, with windlasses c 'c, and ropes (l cl, the whole operating in the manner and for the purpose specified.

In witness whereof, I have hereunto. signed my name,-iu the presence of two subscribing witnesses. ROBERT GLOVER.
